Effects of benzene on growth, fat content, and caloric content of striped bass, Morones saxatilis
The aromatic hydrocarbon, benzene, is one of the major water-soluble components and one of the most toxic components of petroleum. Experiments were carried out to determine if sublethal levels of benzene, although not inducing death, would inhibit efficient energy utilization by the striped bass, Morone saxatilis, as measured by growth (wet weight, dry weight), fat content, and caloric content. The effects of benzene exposure were hyperactivity, inability to feed, and impairment of the nervous system. Definite effects of benzene on growth parameters were noted at 6.0- and 3.5-..mu..l/liter levels. Although the fish may be able to adapt by metabolic detoxification and depuration of benzene and metabolites, after more prolonged periods the competitive effects on energy utilization may not only decrease growth but also increase mortality or reduce ability to withstand environmental stress.
